Abstract :
This short paper describes the design of an inexpensive, simple, and reliable solid-state hot-wire anemometer feedback controller for the measurement of turbulence spectra. A summary of the linearized feedback control theory for the application of an operational amplifier in maintaining the active element in a balanced bridge configuration of a hot-wire anemometer at constant temperature is presented.
